6 XML::LibXML::AttributeHash - tie an XML::LibXML::Element to a hash to
7 access its attributes
8
10 tie my %hash, 'XML::LibXML::AttributeHash', $element;
11 $hash{'href'} = 'http://example.com/';
12 print $element->getAttribute('href') . "\n";
13
15 This class allows an element's attributes to be accessed as if they
16 were a plain old Perl hash. Attribute names become hash keys.
17 Namespaced attributes are keyed using Clark notation.
18
19 my $XLINK = 'http://www.w3.org/1999/xlink';
20 tie my %hash, 'XML::LibXML::AttributeHash', $element;
21 $hash{"{$XLINK}href"} = 'http://localhost/';
22 print $element->getAttributeNS($XLINK, 'href') . "\n";

24 There is rarely any need to use XML::LibXML::AttributeHash directly. In
25 general, it is possible to take advantage of XML::LibXML::Element's
26 overloading. The example in the SYNOPSIS could have been written:
27
28 $element->{'href'} = 'http://example.com/';
29 print $element->getAttribute('href') . "\n";
30
31 The tie interface allows the passing of additional arguments to
32 XML::LibXML::AttributeHash:
33
34 tie my %hash, 'XML::LibXML::AttributeHash', $element, %args;
35
36 Currently only one argument is supported, the boolean "weaken" which
37 (if true) indicates that the tied object's reference to the element
38 should be a weak reference. This is used by XML::LibXML::Element's
39 overloading. The "weaken" argument is ignored if you don't have a
40 working Scalar::Util::weaken.
